Comment (by tobias):
I like the new logic in 1.5, but I still think you should be able to apply
the `DO_NOTHING` logic on a per-query basis, rather than having to use
whatever policy you set in the `ForeignKey` declaration across the project
as a whole. For example, if I know I'm going to be deleting millions of
rows, I'll want to enable this, but for normal use at just about every
other point in my project, the default behavior is preferable. Could we
just add something like a `force_fast` option to the `delete()` method
that basically did the same thing as having `DO_NOTHING` on every foreign
key in the model being deleted?
For others who stumble upon this ticket and wonder how the new code in 1.5
works, here's a link to the docs:
